DETAILED DESCRIPTION

[0029] See also Figure 1-Figure 10In an embodiment of the present invention, a surface treatment device for gluing an electric vehicle frame includes a box body 1. Preferably, support plates 2 are fixedly arranged at the centers of both ends of the top of the box body 1, and a first slide groove 14 is arranged on one side of the support plate 2 close to the center of the box body 1, and the first slide groove 14 extends to the inner wall of the box body 1, and a limit plate 11 is slidably arranged in the first slide groove 14, and a mounting member 4 is rotatably arranged on the limit plate 11, and a clamping assembly is arranged at one end of the mounting member 4 away from the support plate 2, and a shaking assembly is arranged in the mounting member 4, and the shaking assembly is matched with the clamping assembly in transmission, and when the shaking assembly rotates, the clamping assembly is prompted to make reciprocating horizontal motion at the end of the mounting member 4.

[0030] It should be noted that in order to keep the two groups of limit plates 11 moving synchronously, a push rod is fixedly arranged on the top of the limit plate 11, and a cross plate is fixedly arranged after one end of the two groups of push rods away from the limit plate 11 slides through the top of the support plate 2, and a telescopic cylinder is arranged at the top center of the cross plate, and the telescopic cylinder is fixedly installed with the support plate 2 or the box body 1 through a bracket. In this way, when the telescopic cylinder is started, it pushes the cross plate, and then the two groups of limit plates 11 are synchronously raised or lowered in the support plate 2 through the push rod. In actual use, when the frame needs to be surface treated, the frame The two ends are fixed by two sets of clamping assemblies, and then the telescopic cylinder is started to drive the limit plate 11 to move into the box 1. The box 1 is used to contain a solution for cleaning the surface of the frame. After the frame is soaked and cleaned in the box 1, the telescopic cylinder is started to move the limit plate 11 to reset, so that the frame is moved away from the box 1 under the action of the clamping assembly. In this process, the clamping assembly is made to reciprocate horizontally at the end of the mounting member 4 through the shaking assembly, so that the frame is shaken, so as to achieve the effect of quickly shaking off the water stains on the frame and accelerate the efficiency of drying the frame.

[0031] See also Figure 1-Figure 6 Preferably, the shaking assembly includes a driving shaft 15; the driving shaft 15 is rotatably arranged in the mounting member 4, a boss 19 is fixedly arranged at one end of the driving shaft 15 close to the clamping assembly, a square frame 16 is arranged on the periphery of the boss 19, and the square frame 16 is fixedly connected to the clamping assembly at one end away from the driving shaft 15.

[0032] Furthermore, preferably, the inner wall of the support plate 2 is provided with an extension groove 13 connected to the first slide groove 14, the extension groove 13 is arranged on the side of the first slide groove 14 away from the clamping assembly, and a pull rope 18 is fixedly provided on the periphery of one end of the drive shaft 15 away from the mounting member 4, and the end of the pull rope 18 away from the drive shaft 15 is fixedly connected to the bottom end of the extension groove 13.

[0033] It should be noted that: the mounting member 4 specifically includes a first cylinder, and a first disc is fixedly arranged at one end of the first cylinder away from the support plate 2. The first cylinder is rotatably connected to the center of the limit plate 11, and the protrusion 19 is arranged at one end of the first disc away from the first cylinder. The specific structure of the drive shaft 15 is an "I"-shaped cylindrical structure. The drive shaft 15 is rotatably embedded in the mounting member 4, and the square frame 16 is slidably arranged in the first disc on the mounting member 4. The end of the drive shaft 15 away from the clamping assembly slides through the end of the mounting member 4 and extends into the extension groove 13. The pull rope 18 is also arranged A torsion spring is arranged in the extension groove 13 and between the outer periphery of the drive shaft 15 and the inner wall of the mounting member 4. The torsion spring is arranged to enable the drive shaft 15 to rotate without being subjected to force. The first disc of the boss 19 on the mounting member 4 is eccentrically arranged. The height of the square frame 16 is greater than the vertical range of the rotation trajectory of the boss 19 around the first cylinder, and the width of the square frame 16 is less than the horizontal range of the rotation trajectory of the boss 19 around the first cylinder. In this way, when the boss 19 revolves around the mounting member 4, the square frame 16 can be prompted to perform horizontal reciprocating motion.

[0034] In actual use, in the initial state, the limit plate 11 is at the top of the first slide groove 14 under the action of the telescopic cylinder, the pull rope 18 is in a straight state, the torsion spring between the drive shaft 15 and the mounting member 4 is in a stressed state, and the clamping assembly is in a relatively static state; when the frame is fixed by the clamping assembly, the limit plate 11 is started to move toward the box body 1, and then the workshop is moved into the solution in the box body 1, so as to perform an immersion cleaning treatment on the surface of the workshop. In this process, the limit plate 11 drives the mounting member 4 and the drive shaft 15 to move downward, so that the pull rope 18 is gradually in a relaxed state, and the torsion spring between the drive shaft 15 and the mounting member 4 will rotate and reset at this time, thereby driving the drive shaft 15 to rotate, and the rotation of the drive shaft 15 To realize the winding work of the pull rope 18, when the cleaning process of the frame is completed and the limit plate 11 is started to move upward and reset, during this process, since the bottom end of the pull rope 18 is fixed to the bottom end of the extension groove 13, and the pull rope 18 is wound around the outer end of the driving shaft 15, when the limit plate 11 moves to drive the driving shaft 15 to move upward, the pull rope 18 will spread out from the driving shaft 15, thereby causing the driving shaft 15 to rotate. The rotation of the driving shaft 15 drives the boss 19 to rotate. The rotation of the boss 19 causes the clamping assembly to reciprocate horizontally at the end of the mounting member 4 through the action of the square frame 16, thereby achieving the effect of shaking the frame under the cooperation of the two sets of clamping assemblies, thereby accelerating the falling of water stains on the frame and improving the drying efficiency of the frame.

[0035] See also Figure 4-Figure 5Preferably, a square block is fixedly provided on the periphery of one end of the mounting member 4 away from the clamping assembly, and the square block is slidably adapted to the first slide groove 14, so that when the driving shaft 15 rotates under the action of the pull rope 18, the mounting member 4 avoids the possibility of rotation through the cooperation between the square block and the first slide groove 14, thereby effectively allowing the driving shaft 15 to rotate.

[0036] See also Figure 1-Figure 2 , Figure 4-Figure 5 Preferably, a rack 8 is provided at the bottom end of one side of the first slide groove 14, and the rack 8 is elastically connected to the inner wall of the box body 1. A gear 17 corresponding to the rack 8 is provided on the periphery of the mounting member 4, and the gear 17 is arranged between the square block and the limiting plate 11. Preferably, the top height of the rack 8 is slightly higher than the top height of the box body 1, and the bottom of the rack 8 is elastically connected to the inner wall of the box body 1 through a spring, and the gear 17 and the periphery of the mounting member 4 are matched through the transmission structure of the ratchet pawl, so that the mounting member 4 is driven to rotate by the gear 17 only when the rack 8 moves upward, and the mounting member 4 cannot be driven to rotate when the rack 8 moves downward. The ratchet pawl is a prior art, and the specific structure and related working principle will not be described in detail here.

[0037] See also Figure 2 , Figure 4 Preferably, a transmission disk 7 is rotatably provided on the inner wall of the box body 1, and the transmission disk 7 is arranged at the bottom end position of the extension groove 13 and the first slide groove 14. A notch is provided on the transmission disk 7, and the end of the pull rope 18 away from the driving shaft 15 is fixedly connected to the notch. Preferably, the size of the notch matches the size of the extension groove 13 and the first slide groove 14, and a counterweight block is provided in the side wall of the transmission disk 7 away from the notch. Through the setting of the counterweight block, the transmission disk 7 is realized in the initial state. The opening of the notch corresponds to the extension groove 13 and the first slide groove 14, thereby facilitating the downward movement of the mounting member 4 to be in the notch.

[0038] In actual use, in the initial state, the limit plate 11 and the mounting member 4 are at the top position in the first slide groove 14, the opening of the notch corresponds to the extension groove 13 and the first slide groove 14, and the top of the rack 8 is at a height slightly higher than the top of the box body 1 under the action of the corresponding spring; then, when the surface of the frame needs to be processed, the two ends of the frame are fixed by the clamping assembly, and then the telescopic cylinder is started to push the limit plate 11 downward, thereby driving the mounting member 4 to move, and then allowing the frame to move into the box body 1. When the limit plate 11 moves to the bottom end position of the first slide groove 14, the ends of the square block and the drive shaft 15 move into the notch. At this time, the center of the mounting member 4 is concentric with the center of the transmission disk 7, and in the process of the limit plate 11 moving downward, the gear 17 will contact and cooperate with the top of the rack 8, but at this time, because the square block and the first slide groove 14 are slidingly adapted, the rack 8 cannot act on the gear 17 to drive the mounting member 4 to rotate The gear 17 pushes the rack 8 downward, thereby compressing the spring at the bottom of the rack 8. When the square block is in the notch, the rotation direction of the mounting member 4 is no longer restricted, so the rack 8 will move upward under the action of the spring reset at its bottom, and then drive the mounting member 4 to rotate through the gear 17. The rotation of the mounting member 4 drives the clamping assembly to rotate, so that the frame in the box body 1 rotates in the box body 1, thereby increasing the impact of the liquid on the surface of the frame and improving the efficiency of the surface treatment of the frame. After the rack 8 moves and resets, the transmission disc 7 will automatically adjust to the position of the first slide groove 14 corresponding to the notch opening under the action of the counterweight block, thereby facilitating the movement and reset of the limit plate 11. Subsequently, when the surface treatment of the frame is completed, the telescopic cylinder is started to drive the limit plate 11 to move and reset. During the reset process of the limit plate 11, the shaking effect of the frame is achieved through the cooperation of the drive shaft 15 and the pull rope 18.

[0039] See also Figure 1-Figure 2 , Figure 7-10 Preferably, a scraper 6 is provided on one side of the bottom of the box body 1, a fixed column is provided on one end of the scraper 6, and a slider 26 is slidably connected to the end of the scraper 6 away from the fixed column. A guide rail 5 slidably connected to the fixed column is provided on the inner wall of the box body 1, and a second slide groove 21 slidably connected to the slider 26 is provided on the inner wall of the box body 1 away from the guide rail 5, and a collecting box 22 is provided on the side of the bottom of the inner wall of the box body 1 away from the scraper 6.

[0040] Preferably, the two ends of the scraper 6 correspond to two groups of support plates 2 respectively, and one end of the scraper 6 can slide in the vertical direction on the slider 26. The guide rail 5 includes an upper half and a lower half. The upper half is arranged above the lower half. The upper half and the lower half are both arranged in a horizontal straight structure. A lifting section is arranged at one end of the upper half and the lower half close to the collecting box 22, and a descending section is arranged at one end of the upper half and the lower half away from the collecting box 22. The connection between the upper half and the lifting section is located at the center of the collecting box 22.

[0041] In actual use, in the initial state, the scraper 6 is at the lower half of the guide rail 5, away from the end of the collection box 22. At this time, the bottom of the scraper 6 slides and fits with the bottom of the inner wall of the box body 1, and the top of the collection box 22 is flush with the bottom of the inner wall of the box body 1. When the scraper 6 moves toward the collection box 22, the scraper 6 scrapes off the impurities and other particles deposited on the bottom of the box body 1. When the scraper 6 moves to the lifting section through the fixed column, the scraped impurities will fall into the collection box 22 and be collected. The rising section enters the upper half of the guide rail 5, and at this time the slider 26 moves in the second slide groove 21 to one end close to the collection box 22. When the fixed column moves to the upper half of the guide rail 5, the scraper 6 then moves to reset. Since the upper half is above the lower half, the bottom of the scraper 6 will be separated from the bottom of the box body 1, thereby avoiding the problem of scraping impurities on the bottom of the inner wall of the box body 1 to the side of the box body 1 away from the collection box 22 when the scraper 6 moves away from the collection box 22, causing accumulation.

[0042] Furthermore, preferably, a cover plate 20 is provided on the top of the collecting box 22, and one end of the cover plate 20 away from the scraper 6 is elastically connected to the side wall of the box body 1, and a top block 9 is symmetrically provided along the center on one side of the scraper 6 close to the collecting box 22, and the bottom of the end of the top block 9 close to the cover plate 20 is a chamfered structure. Preferably, the cover plate 20 is provided to seal the top of the collecting box 22, thereby preventing the stirred water flow from carrying out the impurities collected in the collecting box 22 when the frame is subjected to surface cleaning treatment in the box body 1, and the top block 9 is provided to push the cover plate 20 away from the collecting box 22 in advance when the scraper 6 moves toward the collecting box 22, thereby exposing the collecting box 22, thereby achieving effective and rapid collection of impurities.

[0043] Furthermore, preferably, a telescopic tube 23 is fixedly provided at one end of the slider 26 away from the collecting box 22, the telescopic tube 23 is slidably embedded in the side wall of the box body 1, and the end of the telescopic tube 23 away from the slider 26 is fixedly connected to the inner wall of the box body 1, and an airbag 25 is fixedly provided at the bottom of the rack 8, the bottom of the airbag 25 is fixedly connected to the inner wall of the box body 1, a connecting tube 24 is provided between the airbag 25 and the telescopic tube 23, the airbag 25 and the telescopic tube 23 are connected through the connecting tube 24, preferably, the telescopic tube 23 can be provided as an elastic telescopic structure to realize an automatic contraction function when not subject to force, and the airbag 25 is sleeved on the periphery of the spring at the bottom of the rack 8.

[0044] When in use, in the initial state, the limit plate 11 is at the top position of the first slide groove 14, the rack 8 is close to the top position of the box body 1, the airbag 25 is in an expanded state, the telescopic tube 23 is in a contracted state, the slider 26 is close to the end of the second slide groove 21 away from the collection box 22, the cover plate 20 blocks the collection box 22, the fixed column is in the lower half of the guide rail 5, and the bottom of the scraper 6 is in contact with the bottom of the inner wall of the box body 1; when the limit plate 11 is started to move downward, the gear 17 will cause the rack 8 to move downward, and the downward movement of the rack 8 will squeeze the airbag 25, so that the gas in the airbag 25 is transported to the telescopic tube 23 through the connecting tube 24, so that the telescopic tube 23 expands and stretches, and then pushes the slider 26 to move in the direction of the collection box 22, thereby realizing the movement of the scraper 6 in the direction of the collection box 22 and the box body 1 The bottom of the inner wall is scraped and cleaned. When the limit plate 11 moves to the bottom end of the first slide groove 14, the slider 26 moves to the end of the second slide groove 21 close to the collection box 22. At this time, the fixed column moves through the lifting section of the guide rail 5 and enters the upper half position. The top block 9 and the cover plate 20 cooperate with each other to collect impurities before the frame enters the box body 1 and the rack 8 moves upward to drive the mounting part 4 to rotate. The problem of impurities precipitated at the bottom of the box body 1 being attached to the frame again due to the stirring of the water flow by the frame rotation is avoided. When the rack 8 moves upward and resets, the telescopic tube 23 elastically contracts and resets under the negative pressure generated by the reset of the airbag 25 and its own elastic action, thereby driving the slider 26 to move and reset, so that the scraper 6 moves and resets for the next use.
